Flashing the Boot ROM for the MV6100 Using Motorola MotLoad
-----------------------------------------------------------

The MVME6100 boards come with the Motorola MotLoad firmware installed 
in BOTH the FLASH banks.  This firmware can be used to download and FLASH 
the VxWorks bootrom into either of the FLASH banks. This way one bank will
always contain the Motload firmware and the other will contain the 
vxWorks boot kernel.

Which bank will be the default loaded at boot/power-up is defined by a 
small 4 position toggle-switch on the board (switch S4 - upper right
quadrant). position 2 defines "BOOT A" or "BOOT B" specifying whether
Flash Bank 0 or 1 respectively will be the default.

On power-up the following will be displayed on the serial/debug port:

--------------

  At the MVME6100> prompt several commands can be issued. First, if this
is the first time the board has been powered up the real time clock must
be started:

MVME6100> time
(Clock is not ticking)
MVME6100> help set
Usage: set [-dPs] -tPs
Description: Set Date and Time
Argument/Option Description:
-d  Ps: Device Name (Default = /dev/rtc)
-t  Ps: Date/Time String (MMDDYYHHMMSS)
MVME6100> set -t082604163100
MVME6100> time
THU AUG 26 16:31:02.00 2004
MVME6100> 

Then one can confirm which Flash Bank is the boot bank:

MVME6100> flashShow
Device-Name  Base-Address,Size  Device-Size,Count  Boot  Type
/dev/flash0  F4000000,04000000  02000000,00000002  No    Intel 28F256
/dev/flash1  F8000000,04000000  02000000,00000002  Yes   Intel 28F256
MVME6100> 

The above indicates that Bank 1 (B) the the boot bank so that we can safely
Flash the vxWorks boot kernel into Bank 0 (A)

The boot file is transferred from a TFTP host to the target board using
the `tftpGet' command.  IMPORTANT: You must have a TFTP server running
on your host's subnet for the `tftpGet' command to succeed.  The file
name must be set to the location of the binary file on the TFTP host.
The binary file must be stored in the directory identified for TFTP
accesses, but the file name is a relative path and does not include
the "tftpboot" directory name.

The MVME6100 has two Ethernet ports defined by the device names
"/dev/enet0" and "/dev/enet1". The port on the front panel next to the
debug port is enet0 and is the default one to use.

To download the boot file: (you will of course have to supply the IP
addresses for your system...)

MVME6100> tftpGet -c129.57.29.155 -s129.57.29.101 -fboot6100_v122.bin 
Network Loading from: /dev/enet0

Client IP Address      = 129.57.29.155
Server IP Address      = 129.57.29.101
Gateway IP Address     = 0.0.0.0
Subnet IP Address Mask = 255.255.255.0

After the file is loaded onto the target, the `flashProgram' command is used
to put it into specified FLASH Bank:

MVME6100> flashProgram -d/dev/flash0 -o03f00100 -nfff00
Source Starting/Ending Addresses      =006B7000/007B6EFF
Destination Starting/Ending Addresses =F7F00100/F7FFFFFF

When the flashProgram command is finished, power down the board and switch 
boot banks - this is controlled via switch S4 position 2.  

Then power the board back up. You should see the vxWorks Boot begin...
